Key advantages of this solution include:

• Optimally selected wire geometry – routing the harness according to the factory path, without stress or unnatural bends.
• Dedicated connectors for PDC sensors – eliminating the need for modifications or soldering wires.
• Compatibility with the factory diagnostic system – accurate reading of sensor errors and operating parameters.

Service Application and Installation

The front bumper PDC sensor wiring harness is particularly useful in situations where:

• the wiring was damaged during a collision or bumper replacement,
• the original wires have been broken, corroded, or exposed to mechanical damage,
• intermittent parking sensor errors occur due to an open circuit.

A properly selected, original harness simplifies service work – installation is performed similarly to the factory method, utilizing existing brackets and guides. This is a practical solution for both professional workshops and users who care about maintaining the integrity of the electrical system in their Mercedes.

Product Characteristics and Condition

The offered harness belongs to the Wires, Harnesses, and Connectors group dedicated to the Mercedes brand. The product is used, allowing for an economical restoration of the PDC system's functionality while maintaining the original manufacturer's specifications. This type of component is particularly useful for post-accident repairs where replacing the bumper alone is not sufficient to fully restore the parking assist system's functionality.
